RFC 5462 MPLS TC Field Definition February 2009 This paragraph is now changed to: 3. Traffic Class (TC) field This threebit field is used to carry traffic class information, and the change of the name is applicable to all places it occurs in IETF RFCs and other IETF documents. mpls traffic class rfc Multiprotocol Label Switching (MPLS) Label Stack Entry: EXP Field Renamed to Traffic Class Field (RFC 5462, February 2009) Toggle navigation Datatracker Groups This document changes the name of the field to the Traffic Class field ( TC field ). In doing so, it also updates documents that define the current use of the EXP field.
MultiProtocol Label Switching Networks Is there a qualityofservice (QoS) architecture for MPLS? The format of the MPLS shim header is defined in RFC 3032. That definition reserves 3 bits for experimental use. Class 1 is used for realtime traffic, class 4 is used for besteffort traffic, and out of the two additional classes, one is mpls traffic class rfc
RFC 3272 Overview and Principles of Internet TE May 2002 traffic across multiple feasible routes, and the multiplexing of IP traffic over traffic trunks (if such constructs exists) and over the underlying network infrastructure. A network topology model is a necessity for routing analysis. Network Working Group K. Kompella Request for Comments: 4201 Y.

Berger Movaz Networks October 2005 Link Bundling in MPLS Traffic Engineering (TE) Status of This Memo This document specifies an Internet standards track protocol for the Internet community, and requests discussion and suggestions for However, until recently, MPLS QoS markings have always made use of a field in the MPLS label header designated Experimental (Exp) as defined in RFC 3032. Recently released RFC 5462, a proposed standard, renames the Experimental field to the Traffic Class (TC) field. mpls traffic class rfc This guide presents extensions made to Multiprotocol Label Switching Traffic Engineering (MPLS TE) that make it DiffServ aware. Specifically, the bandwidth reservable on each link for (RFC 4125). The new concept of ClassType defined in the IETF Standard corresponds to the prior concept of bandwidth pool that was implemented in the RFC 2702 MPLS Traffic Engineering September 1999 2. 0 Traffic Engineering This section describes the basic functions of Traffic Engineering in an Autonomous System in the contemporary Internet. The limitations of current IGPs with respect to traffic and resource control are highlighted. RFC 4128 BC Models for Diffservaware MPLS TE June 2005 1. Introduction Differentiated Services (Diffserv)aware MPLS Traffic Engineering (DSTE) mechanisms operate on the basis of different Diffserv classes of traffic to improve network performance.
